New study on carb intake with weight loss

I didnt copy the link as I believe thats against the terms and conditions of this site. so i copied what was on it.. please read..interesting subject

Dieters who can’t stomach the idea of going hungry seven days a week just got good news: You might be able to drop more weight if you cut back on carbs just two days a week.

British researchers found that women who essentially gave up carbs for two days and ate normally the rest of the time dropped about 9 pounds on average, as compared to the 5 pounds lost by women who cut back to around 1,500 calories every day, according to a report presented at the CTRC-AACR San Antonio Breast Cancer Symposium.

“We came up with the idea of an intermittent low-carb diet because it enables people to still have foods that are very satiating,” said the study’s lead author Michelle Harvie, a research dietician at the Genesis Prevention Center at the University Hospital in South Manchester, England. “Also, there’s a lot of evidence from other studies showing that restricting carbohydrates has the same effect as restricting energy.”

Harvie and her colleagues were spurred to find a diet that would be easier for women to follow because research has shown that obesity and the changes it causes in the body increase the risk for breast cancer. “We know from our research in animal models that losing weight has the potential for reducing breast cancer risk,” Harvie said.



The researchers followed 88 women for four months. All the women were at high risk for breast cancer based on their family histories.

One third of the women were put on a Mediterranean-type diet that restricted calories to about 1,500 per day. A second group was told to eat normally most of the time, but two days a week to cut carbs and also calories to about 650 on those two days. The third group was also to cut carbs two days a week, but there was no calorie restriction on those days.

At the end of four weeks women in both of the intermittent dieting groups had lost more weight — about 9 pounds — than the women who ate low calorie meals every day of the week — about 5 pounds.

Women in the intermittent dieting groups also had better improvement than daily dieters in the levels of hormones — insulin and leptin — that have been linked with breast cancer risk, Harvie said.

And, yes, this is something you can try at home, Harvie said. You just need to dramatically cut back carbohydrates two days a week and try to eat sensibly the rest of the time, she added.

What that means, Harvie said, is that you can eat protein and healthy fats on the two low carb days, but skip bread, pasta, root vegetables like potatoes, carrots and parsnips to get to the 50g limit. The diet allows for one piece of fruit on the low carb days. Other foods on the menu include: nuts and green, leafy vegetables, peppers, mushrooms, tomatoes, broccoli, eggplant and cauliflower.

    Very interesting. I would be nervous I would gorge myself on non low carb days in anticipation of that kind of restriction. But I just may give this a shot if I hit a plateau. Thanks for sharing!

    Yep, there is a tie between cinnamon and blood sugar control. At least I've heard this before

    agreed :) although I heard this years ago from a Hungarian trainer :) I am pretty much doing it and it works for me.
    Check out my recipes with pics that I eat daily if you need some idea:

    I did some digging on Cinnamon and was disappointed. I had been taking it for a while because I too had read the info that it was supposed to help regulate your blood sugar. Turns out that the study that this idea is based on was terribly flawed and there's no truth to it. Boo...

    No surprise that the group that dropped to 650 for 2 days lost more weight. Need more details on the other group also.

    Details on BF% changes also & exercise performance would be helpful.


    Having said that, this is the basis of what Lyle McDonald's UD2 is based around & there is no doubt that carb cycling works but at the end of the day if you dropped out all carbs & still consumed more than your TDEE you're not going to lose weight. Cutting carbs isn't magic weight loss.

    I want to know the weight of these women and more details. Also I would like to point out A - VERY small sample size. B- The follow up is listed after 4 weeks and they say they followed the women for 4 months. What were the final results?

    Not saying it doesn't work. Just my analytically research oriented mind wants to know more.

    That is called "zigzagging calories".

    I'm curious, what kindlf no-carb food can you eat that will total 650 calories?
    Let's see:
    22 oz of shrimp
    Or
    25 oz tuna
    Or
    12oz steak
    Or
    16oz pork
    Or
    23oz chicken....

    Do you Really want to spend 2 days a week eating ONLY meat, and in that kind of quantity?
    Also, I introduce the concept that each of those mentioned are high protein and that might have also been a contributing factor.
